If a polynomial equation in 
has a root 
, then the polynomial has a factor of 
.
Since it is a quadratic equation you seek and we know that all quadratic equations have two roots, -3.5 and 2.2 represent all of the roots for the desired equation. Therefore the equation can be found by multiplying the two factors:
\right)\left(x\ -\ 2.2\right)\ =\ \left(x\ +\ 3.5\right)\left(x\ -\ 2.2\right)\ =\ 0)
Now all you have to do is FOIL it.
